Allergies aside, what do people reckon on peanut butter as a nutritious food? have just discovered that 13mo ds likes it (tends to suck it off the toast, but never mind), & as he doesn't like other 'quick fix' foods such as baked beans or eggs I was pleased - until I started worrying it wasn't very good for him.
BTW, I use the organic WholeEarth sugar-free sort. Also he gets lots of home-cooked food.
